HTTP POST

HTTP POST requests that the asset at the URI accomplishes something with the given substance. POST is often utilized to make another substance; however, it can likewise be utilized to refresh an element.

Here are the common functions of HTTP POST:

@Throws(RestClientException::class)
fun postForLocation(url: String, request: Any, vararg urlVariables: Any): URI

fun postForLocation(url: String, request: Any, urlVariables: Map<String, *>): URI

@Throws(RestClientException::class)
fun postForLocation(url: URI, request: Any): URI

fun <T> postForObject(url: String, request: Any, responseType: Class<T>, vararg uriVariables: Any): T

fun <T> postForObject(url: String, request: Any, responseType: Class<T>, uriVariables: Map<String, *>): T

@Throws(RestClientException::class)
fun <T> postForObject(url: URI, request: Any, responseType: Class<T>): T

fun <T> postForEntity(url: String, request: Any, responseType: Class<T>, vararg uriVariables: Any): ResponseEntity<T>

@Throws(RestClientException::class)
fun <T> postForEntity(url: String, request: Any, responseType: Class<T>, uriVariables: Map<String, *>): ResponseEntity<T>

@Throws(RestClientException::class)
fun <T> postForEntity(url: URI, request: Any, responseType: Class<T>): ResponseEntity<T>

Here is an example of how to call these functions:

/** POST **/

val restTemplate = RestTemplate()

val baseUrl: String ?= "YOUR_URL"
val uri = URI(baseUrl)
val body = "The Body"

val response = restTemplate.postForEntity(baseUrl, body, String::class.java)

val request = HttpEntity(body)
val responseExchange = restTemplate.exchange(baseUrl, HttpMethod.POST, request, String::class.java)

val responseURI = restTemplate.postForEntity(uri, body, String::class.java)
val responseExchangeURI = restTemplate.exchange(uri, HttpMethod.POST, request, String::class.java)
